It hasn’t been the best quarter for The Home Depot, Inc. (NYSE:HD) shareholders, since the share price has fallen 16% in that time. But at least the stock is up over the last five years. However we are not very impressed because the share price is only up 34%, less than the market return of 82%.

So let’s assess the underlying fundamentals over the last 5 years and see if they’ve moved in lock-step with shareholder returns.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During five years of share price growth, Home Depot achieved compound earnings per share (EPS) growth of 4.8% per year. This EPS growth is slower than the share price growth of 6% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. That’s not necessarily surprising considering the five-year track record of earnings growth.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Dive deeper into the earnings by checking this interactive graph of Home Depot’s earnings, revenue and cash flow.

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Home Depot’s TSR for the last 5 years was 51%, which exceeds the share price return mentioned earlier. And there’s no prize for guessing that the dividend payments largely explain the divergence!

Investors in Home Depot had a tough year, with a total loss of 16% (including dividends), against a market gain of about 14%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 9% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
